Abstract
The results of the use of synchrotron radiation X-ray fluorescence (SRXRF) are demonstrated for simultaneous determination of the multielement composition of human blood, hair and placenta, animal hair, bony and muscular tissues, gallstones and some objects of a food chain (berries, iceland moss, cedar kernels, honey). Concentrations of the following elements were determined: K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Hg, Pb, Bi, Th, U. The technique for preparing biological samples has been developed for determining the element composition by the SRXRF method. The peculiarities of determination of the multielement composition of thin and in form of tablets samples are analyzed. It is shown that SRXRF is fairly informative for estimating the specific features of the multielement composition of biosubstrates.
